PLANETARY GEARBOX Russian patent published in 2002 - IPC

FIELD: mechanical engineering. SUBSTANCE: invention can be used in multiple-speed gearboxes of vehicles. End face of planetary mechanism carrier engages with synchronization ring of under-drive being provided with cylindrical belt setting radial clearance between ring and carrier, with direct shifted-in, smaller than radial clearance between conical surfaces of synchronization ring and underdrive clutch member. Limiting steps are made on crown gear at each wall from side of locking pins to provide stable clearance between conical surfaces. Such design precludes contacting of conical surfaces of synchronization ring and underdrive clutch member. Additional machining of idle surfaces of synchronization ring and balancing of ring are not required. EFFECT: facilitated manufacture of planetary gearbox. 4 dwg
